I have a 2009 IRON 883, no modifications. If the bike sits in the sun all day and the ambient temp. is 100+ (which is not uncommon in Houston) immediately upon start up I get a high pitched whine sound. Closest sound I can think of is a disc brake squeal. This sound is intermittent, does not vary in pitch or frequency with engine revs or bike speed but can be loud or softer and of different durations. OK and here's the REALLY STRANGE part...if the bikes stopped and it's making the noise and I put it over on it's side stand - the noise stops, bring it back up to verticle and it starts again. I'm not delusional - others have witnessed this.
Any other riders experience this - any ideas???
hey there, if you fix your oil levels and still hear the noise...then my guess..without checking it out myself would be your fuel pump....my new 48 makes a squeeling noise sometimes when I hit the button..
